What is a Communication System (CS)?
You tell me the definition(s).
For example, runners, carrier pigeons, drum beats, and torches*, etc.
These are superseded by electrical communication systems, which cantransmit signals over much longer distances (even to distant planets and
galaxies) and at the speed of light.
Communication technology is alleviating the energy crisis ... Can you give afew examples?

Now, can you guess the difference between analog and digital?
If you treat an entire textbook (written in English) as a signal, then is itanalog or digital?
Can you give me an example for one of the oldest binary digital systems?

Pulse Code Modulation (PCM)
Even though PCM is invented as early as 1926, It was the transistor thatmade PCM practicable in early 60s.
Average power of a PCM signal is less. However, the price paid is theincrease in the signal bandwidth.

Power vs Bandwidth
Two primary communication resources are the bandwidth and thetransmitted power. In a given communication channel, one resource may be
more valuable than the other, and the communication scheme should bedesigned accordingly.
